Built on the DA300 collet system with a straight shank, it accepts collets ranging from 1\/64 inch minimum to 1\/4 inch maximum capacity. The 6.80 inch overall length and 1.31 inch projection provide the reach and rigidity needed for accurate tool positioning. Through-spindle coolant compatibility makes this chuck suitable for high-production environments where heat management is critical. Machinists and toolroom technicians install this chuck to secure small-diameter end mills, drills, and reamers in compatible spindles.\u003c\/p\u003e\u003cp\u003eThis collet chuck is suited for use in vertical and horizontal machining centers running the DA300 collet series. With a 1\/2 inch shank diameter and 0.56 inch collet nut diameter, it fits standard DA300-compatible spindle bores. The straight shank design simplifies setup and alignment, making it appropriate for both production shops and job shops handling precision light-duty cutting operations with tooling up to 1\/4 inch in diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDA300 double angle collet system for secure, repeatable tool clamping\u003c\/li\u003e\n\u003cli\u003eMaximum collet capacity of 0.25 inches accommodates common small-diameter tooling\u003c\/li\u003e\n\u003cli\u003eStraight shank with 1\/2 inch diameter for straightforward spindle installation\u003c\/li\u003e\n\u003cli\u003eThrough-spindle coolant compatibility supports high-speed and production cutting\u003c\/li\u003e\n\u003cli\u003e1.31 inch projection provides adequate reach for standard machining clearances\u003c\/li\u003e\n\u003cli\u003e6.80 inch overall length suits typical vertical machining center setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with DA300 series double angle collets in machining centers and milling machines equipped with a compatible straight shank spindle bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before installing or removing the collet chuck. Ensure the shank bore and chuck surfaces are clean and free of chips or burrs before seating.
